Slayer capes are black in colour, and have a red trim if the player has more than one level 99 skill. Kuradal will talk to you when buying a cape, regardless of your combat level, which means she also sells the Slayer cape to players under 110 combat, the level required to get tasks from her. You also need either 45 Firemaking or 15 Strength to enter the cave, with completion of the Barbarian Training to access Kuradal and the Slayer cape.

Talking to Kuradal gives an option to toggle the appearance of the cape to a retro version, overriding the normal appearance and making it look similar to how it did before the 2015 graphical update. Despite it not being a new item, the retro cape can be used with a dragon keepsake key.

Currently, 129,818 people are able to own this cape (as seen on the highscores).

Through the use of experience rewards from lamps, penguin points, zeal, etc; it is possible to achieve 99 slayer at level 3 combat and players are not required to complete the strength activity of barbarian training in order to visit Kuradal and obtain a skillcape. Many skillers 'train' Slayer this way. Reaching 99 Slayer through soul wars and penguin spotting is very slow, however, and will usually take in excess of 4,000 hours of playing time.
